Abstract
The present invention discloses sticky dental compositions and methods for treating sensitive teeth. For maximum comfort, an improved dental tray that is thin-walled, flexible and lightweight is used to hold the dental composition adjacent the desired tooth surfaces. The dental compositions include a sticky matrix material into which is dispersed a desensitizing agent such as KNO.sub.3 and other optional dental agents. The matrix material preferably includes carboxypolymethylene that has been partially neutralized with a base to reduce etching of the enamel. The carboxypolymethylene adds a unique stickiness to the dental composition which helps to adhere and retain the soft tray material against the patient's teeth.
Claims24
A method for treating sensitive teeth comprising:
- (a) providing a dental tray configured to cover a person's teeth and hold a quantity of a dental composition therein, the dental tray further being configured so that it is designed not to exert mechanical pressure onto the person's teeth and gums;
- (b) placing a quantity of a tooth desensitizing dental composition within the dental tray, the dental composition including a desensitizing agent for reducing dental pain sensations and a tackifying agent selected from the group consisting of carboxypolymethylene, gums, proteins, and mixtures thereof;
- (c) positioning the dental tray over the person's teeth for a prescribed treatment period, the dental composition adhering and retaining the dental tray over the person's teeth during the prescribed treatment period;
- and
- (d) removing the dental tray from the person's teeth.
A method for treating sensitive teeth comprising:
- (a) providing a dental tray configured to cover a person's teeth and hold a quantity of a dental composition therein;
- (b) placing a quantity of a desensitizing dental composition within the dental tray, the desensitizing dental composition having a stickiness in order that the dental composition is capable of retaining and holding a dental tray that is designed not to exert mechanical pressure onto a person's teeth and gums over a person's teeth for at least about one hour, the dental composition comprising:
- (i) a desensitizing agent for reducing dental pain sensations;
- and
- (ii) a tackifying agent selected from the group consisting of gums, proteins, carboxypolymethylene, and mixtures thereof;
- (c) positioning the dental tray provided in step (a) over the person's teeth for a prescribed treatment period;
- and
- (d) removing the dental tray from the person's teeth.
A method for simultaneously treating sensitive teeth and diseased gums comprising:
- (a) providing a dental tray configured to cover a person's teeth and gums and hold a quantity of a dental composition therein, the dental tray further being configured so that it is designed not to exert mechanical pressure onto the person's teeth and gums;
- (b) placing a quantity of a desensitizing dental composition within the dental tray, the dental composition including a desensitizing agent for reducing dental pain sensations and a tackifying agent comprising carboxypolymethylene neutralized to a pH in a range from about 4 to about 9;
- (c) positioning the dental tray over the person's teeth and gums for a prescribed treatment period, the dental composition adhering and retaining the dental tray over the person's teeth during the prescribed treatment period;
- and
- (d) removing the dental tray from the person's teeth.
